Residential Solar Panel Installation Site Assessment Checklist

A solar installation assessment covers roof viability, shading audit, and contractor vetting before signing, since these factors determine actual system performance.

Homeowners often get excited about solar savings estimates without first confirming their roof and shading conditions actually support the system's promised output.

Why This Happens

Solar sales quotes are based on ideal conditions, and without an honest site-specific assessment, actual production can fall well short of what was projected.

What's Inside

This checklist is interactive, click to check off items in your browser, plus printable if you'd rather keep it for contractor meetings, and it covers roof structural viability, shading, and contract review before installation begins.

Quick Tips

Check roof age and structural capacity before anything else.

Audit shading across different times of day, not just once.

Frequently Asked Questions

How do I know if my roof is ready for solar?

Roof age, structural capacity, and orientation all factor in, and a roof nearing the end of its life is usually better replaced before installation rather than after.

How much does shading actually affect solar output?

Even partial shading on a portion of the system can meaningfully reduce total energy production, which is why a full shading audit across the day matters.

What is net metering and why does it matter?

Net metering determines how much credit you get for excess energy your system sends back to the grid, and policies vary significantly by utility company.

How many quotes should I get before choosing an installer?

At least 3 quotes helps you compare pricing, equipment quality, and warranty terms realistically before committing to one installer.
